Referrin to the accompanying drawings, throughout which like referencenumerals indicate like parts, 20 and 21 are the two sides, respectively,of a frame, and 22 is a tubular shaft upon which is disposed acylindrical drum 23, the shaft 22 being journaled in suitable bearingboxes 2%, that are provided on the top sides of each of the framemembers 20 and 21, as more clearly shown in Fig. 2, and such shaft '22being connected at each of its ends by suitable swivel couplings 25(only one of which is shown) with pipes 26 that are connected with asource of fluid fuel, as gas, from which tubular shaft 22 gas may flowoutwardly through perforations 27 into the drum 23. such drum 23preferably being divided into two separate compartments by 'a partition28., each 01 such compartments serving as a mixing and pressure chamberfor such gas.

The drum is provided on each end with ti cs 29 and 30 to which aresecured a plurality of outwardly extending channei. sped arms 31 and 32which radiate there from like the spokes of a wheel. The arms 31, whichare secured to the flange 29 on one side of the drum 93, being ofshorter length and extending only part of the to the periphery of amold-carrying wheel which they form a part while the arms that securedto the flange 30 extend to and connect with a circular plate 33, moreclearly shown in Figs. 2 and 4:, which forms a portion of the peripheryof the mold-carrying wheel.

I la, se or the periphery to divide the circumferential'portion of themold carrying wheel into a plurality of separate compartments, suchmembers 34-being secured together at their other ends by a circularlyshaped fluted plate 35 which serves to brace the structure and make itmorerigid and at the same time provides at the ends of the partitionmembers 34 an easy means of gaining access to the compartmentstherebetween.

Within each of the compartments formed by the partition members 34 aredisposed two separable mold members 36 each of which has itsupper-portion articulated witha shaft 37 by a link 38 and its lowerportion articulated with the adjacent partition 34 by a similar link 39,the link 38 being fixedly secured to the shafts 37 whereby saidmoldmembers 36 may be moved apart or may be moved together, as shown in Fig.3, by a rotary movement of the shaft 37 each of the mold members 36being provided on its inner surface with a plurality of recesses 40,herein shown to be six in number, shaped like one half portion of a conethat has been cut on its longitudinal axis, said two mold members 36when moved together, as shown in Fig. 3, being adapted to form a moldcontaining a plurality of conic-ally shaped recesses in each of whichrecesses batter may be baked to form an ice-cream cone.

A transverse bar 41 on which are provided a plurality of cores or coneforming niembers 42, corresponding in form and numbers to the conicallyshaped recesses 40, in the molds '36, is associated with each pair ofsuch molds the bar 41 being secured at each end to guide members 43 thatare adapted to slide within the radially disposed channel shaped arms 31and 32 whereby the cone shaped cores 42 may be moved radially of themold carrying wheel to a position within the mold recesses 40, as moreclearly shown in Fig. 3, or may be withdrawn from "such mold recesses,as shown in Fig. 1, the

guide members 43 each having a short link 44 pivotally connectedtherewith, such short link 44 being articulated with one end of a longerlink 45 that has its other end fixedly secured to a shaft 46 wherebyrotary movement of the shaft 46 will cause the guide members 43 to movelengthwise within the herein illustrated are adapted to be heated by agas flame, the gas that heats the cores 42 being conducted from onecompartment of the drum 23 through pipes 49, 50, 51 and 52 which arepreferably united with each other by ground joint unions 53 in suchmanner that they form a flexible connection with a transverse pipe 54that isad-apted to extend lengthwise along the core-carrying bar 41 at aslight distance inwardly therefrom, such pipe 54 being provided with aplurality of perforations 55, more clearly shown in Fig. 12', which areadapted to emit a jet of gas outwardly intoeach ofthe hollow cone shapedcores which gas may be ignited to burn and heat said core, while the gasthat heats the mold members 36 is conducted from another compartment inthe drum 23, through pipes 56, 57, 58 and 59 which are preferablyconnected with each other by ground joint unions 60 in such manner-thatthey form a flexible connection with two transverse pipes 61 which pipes61 are provided with perforations (not shown) similar to theperforations 55 and are suitably located one on each side of-the corecarrying bar 41 in positions to adapt them each to emit gas outwardlyinto the space between the outside surface of the mold membars 36 andthe adjacent partitions 34 where such gas may be ignited to burn andheat the members 36.

The pipe 49 is provided at a suitable point with a regulating valve 62by which the supply of gas thatis delivered to the pipev 54 may beregulated or may be entirely shut off and the pipe 56 is provided with avalve 63 to which is secured a T shaped handle 64, as more clearly shownin Figs. 2 and 4,

which handle 64 is adapted to be engaged by a pin 65 to close such valveand by another pin 66, which is located at a different point,

to open such valve, as the mold carrying wheel revolves, the pins 65 and66 being secured in brackets 68 and 69 respectively, that are fastenedto the frame 21, as more clearly shown in Fig. 4, and such bracketspreferably being independently adjustable whereby the pins 65 and 66 maybe so set that they will cause the gas in the pipes 61, 61 to be shutoff at any desired point during a rotation of the mold carrying wheeland to con tinue shut off for any desired portion of such rotation, thepipes 50, 51, 57 and 58 approaching alinement, as shown by full lines inFig. 2, when the core carrying bar 1 41 is moved outwardly and assuminga position substantially, as shown by broken lines in Fig. 2, when thecore carrying bar 41 is withdrawn.

The shafts 46-which are connected by the levers 44 and 45 with the corecarrying bars 41 are adapted to extend through a bearing plate 70 on theside of the mold carrying wheel and have lever arms '71 secured to theirouter ends, such shafts 16 being alternately staggered in theirpositions in the plate 70 to afford freedom of movement for the leverarms 71 and the lever arms 71 that are connected with the outermost ofsaid shafts 16 being provided on their free ends with rollers 72 thatare disposed to be engaged by cams '73, 74 and 75, as indicated bybroken lines in Fig. 1, and more clearly shown in Fig. 6, to move suchlever arms 71 and impart rotary movement to the shafts 16 to raise andlower the cores 42 while. the lever arms 71 that are connected with theinnermost of said shafts are articulated with links 7 6 upon which areprovided cam rollers 77 similar to the cam roll.- ers 72 and adapted toengage with the same cam surfaces 73, 71 and 75, the links 76 beingarticulated with other links 7 8 that are pivotally secured to the platewhereby when the cam rollers 77 are moved by contact with the camsurfaces 73, 71 and 75 rotary movement will be imparted to the shafts-16 connected therewith and the mold cores as will be raised or lowered.

The lever arms 71 are preferably adjustably secured to the shafts 4.6and such lever arms 71 are each adapted to be locked in a closedposition by a spring catch 79 that. is adapted to engage with a hook.80. that is provided on the lever arm 71, as more.

clearly shown in Fig. 5, the catch 79 being so positioned that it may beengaged by the rounded surface of an outwardly projecting cam 81 that isprovided on the cam plate 82, as shown in Fig. 5, to release the arm 71.

The shafts 37 which by their turning impart movement to the links 38 tospread the mold members 36 of each of the two part molds apart, arearranged in pairs and disposed to extend outwardly through the plate 33and have sector gears 83 and 84: that are adapted to mesh with eachother securedthereto, one shaft of each pair of the shafts 37 having alever arm 85 secured thereto, which lever arm 85 is provided with a camroller 86 that is adapted to be engaged and moved by cams 87 and 88 onthe cam plate 82 to impart a rotary movement to the shaft 37 thusrotating the sector 83 through a portion of a revolution whereby suchsector 83 will cause the sector 8-1 with which it is in mesh to rotatein an opposite direction through a portion of a revolution, the twoshafts 37 of each pair of shafts thus rotating in opposite directions tospread the molds 36 apart or move such molds together; I

A locking device consisting in a spring catch 89, similar to the catch 79 and adapted to engage with a hook (not shown) on the lever arm 85which is similar to the hook 80 on the lever arm 71, is provided to lockcam plate 82 to release the spring catch 89 at the proper instant oftime to permit the cam 87 to open the molds 36.

The plate 33 is provided on its outer periphery with gear teeth 98 thatare adapted to mesh with the gear teeth of a pinion 91 which is securedto a shaft 92 that extends through theframe 21 and is provided at apoint on the outside of such frame with a large gearwheel93 that isadapted to mesh with a smaller gearwheel 91 which is secured to a shaft95 and in turn is adapted to mesh with another smaller gear wheel 96that is provided on a driven shaft 97 whereby when the shaft 97 isrotated by any desired source of power (not shown) motion will betransmitted through the gearwheels 96, 9 1 and 93 to the pinion 90 todrive the mold carrying wheel of which the circular plate 33 forms aportion.

A batter tank 100 which is connected by a passageway 101 with a tube 102having the shape of an inverted letter U through which batter under alow pressure may be caused to flow is provided with a fioat valve 103,as clearly shown in Fig. 14, whereby when the batter within such tank100 shall have reached a certain predetermined height the valve 103 willclose the passageway 101 and the batter will be caused to flow upwardlyaround the U shaped end of such tube and return to the source of supply(not shown) from which such batter is taken, the batter thus circulatingconstantly in the tube 102 whereby when the float valve 103 is openedslightly by the removal of batter from the tank 100 more batter willimmediately flow into such tank thus keeping the pressure at the outletof such tank, which is in its bottom side constant, such outlet beingconnected with a casing 104. which forms a portion of adepositing devicethat is adapted to extend across the mold carrying wheel near its lowerperiphery in such position, as illustrated in Figs. 1 and 12, that'itshall be directly above the molds 36 when the cores 42 are in a raisedposition whereby batter may be deposited in such molds.

The casing 104 is divided into two compartments 105 and 106 by a wall107 such wall 107 being provided with a plurality of equidistantlyspaced perforations 108 through which batter may flow, such batter beingallowed to flow into the compartment 103 through a passageway 109 thatcommunicates with the tank 100.

Within the compartment 106 are disposed three batter ejecting members110, 111 and 112 shaped like angle bars, as more clearly illustrated inFigs. 15, 16 and 17, the members and 112 being adapted to slide endwisewithin the compartment 105 and the member 111 being fixedly securedwithin such compartment, such member 111 being that the partitions 113snugly fit within the 7 member 112 and the partitions 114 snugly 1 fitwithin the member 111, as more clearly shown in Fig. 13. The side of thefixed member 111 is provided with aplurality of perforations 115'thatregister with the perforations 108 and the bottom of such member 111is provided'with a plurality of simi lar perforations 116 that registerwith perforations 117 that are provided in the bot L tom wall of thecompartment 106, the member 110 being interposed between thememher 111and the walls of the receptacle 106, the side wall of such member 110being pro vided with a plurality of perforations 118, that are adaptedwhen such member 110 is in one position to register with theperforations 108, and the bottom wall of such member 110 being providedwith a plurality of similar perforations 119 that are adapted when suchmember 110'is in a different position to register with the perforations117 that are provided in the bottom wall of the compartment 106, theopenings 108 being closed by the member 110 when the openings I 117 areopened and vice versa.

with one arm of a bell crank shaped actuating member 124 that is adaptedto be oscillated about its pivot point 125 by a rotatably mounted cam126 which is secured to a shaft 127 that is connected by a bevel gear128 with the driving mechanism of the machine, as more clearly shown inFig. 1. The cam 126 being adapted in its rotation to wipe first one armand then the other arm of the actuating member 124 to cause the bar 120to move backwardly and forwardly within the guides 121 and 122 to movethe member 110.

' The member 112 is secured to the end of a bar 129 that is similar tothe bar 120 and is similarly disposed to slide in the guides 121 122,such bar 129 being provided with a pin 130 that is adapted to projectthrough a slot 131 which s provided in a bell crank shaped actuatingmember 132 that is adapted to be oscillated about its pivot 133 by arotatably mounted cam 134 which is similar to the cam 126 and is securedto the same shaft 127 whereby the movement of the two bars 120 and 129may have a fixed relation with respect to time, the actuating member 132being provided with an arm 135 that may be adjusted by moving a screw136 to vary the length of stroke of the bar 129 thus posed that thecenter of each of the cone shaped recesses '40 will pass directly underone of such perforations just after the mold sections 36 have passed thelowermost point in their movement of rotation and have been closed bythe action of the cam 87.

The rotation of the shaft 127 bears. a fixed relation to the movement ofthe molds 36 and as each mold approaches the casing 104 the member 110is' moved backwardly by the action of the cam 126 thus causing theperforations 118 to register with the perforations 108 and as soon assuch perforations are thus caused to register the cam 134 acts to movethe member 112 backwardly thus by the action of the partition 114creating a suction that draws a charge of whereupon the member 110 ismoved forwardly by the action of the cam 126 sufficiently to close theperforations 108 and to cause the perforations 119 in the bottom of themember 110 to register with the holes 117 in the bottom of thecompartment 106 and at the same time that the perforations 117 areopened the'member 112 is moved forwardly by the action of the cam 134thus causing the partitions 114 to serve as pistons to eject asuflicient charge of batter downwardly through each of the holes 117into the conical recesses within the mold members 36 to form anice-cream cone, the

movements of the depositing device being so timed that each successivemold shall receive its deposit of batter as it passes such depositingdevice.

Afterrthe molds 36 have passed the depositing device the cores 42 areautomatically thrust into such molds to form cones of the batter thathas been deposited therein, such batter in its conical form then beingbaked by the heat of a gas flame for the larger part of one revolutionof the mold carrying wheel and the baked cones then being automaticallydischarged by the separating of the mold sections 36 onto a groovedguide member 138 at a point slightly in advance of the mold carryingwheel, the grooved guide member 138 serving. to guide such conesseparately into circular holes 139 provided in the cross bars 140 of atraveling convever, such cross bars 140 being secured at both ends tochains 141 that are adapted to engage with and move over suitable drivensprocket wheels 142 and other idler sprocket wheels 143. as more clearlyshown in Figs. 1 and 8 each of the cones 144 being adapted by reasonfofjfits shape to have its top edge engaged with the circumference ofone of the holes 139,-to hold such cone in a suspended osition, as moreclearly shown in Fig. 7, until such cone 144 shall have been punched outof such hole 139 by the downward movement of a cylindrical punchingmember 145, a plurality of such punching members 145 being associatedwith a vertically movable transverse bar 146 which bar 146 is slidablymounted at each end on vertical standards 147 andis adapted to be movedupwardly and downwardly by lever arms 148 that are fulcrumed on uprightframe pieces 149 and v are connected with such cross .bar .146 by links150, one of such lever arms having its outer end connected by a link 151with one arm of a bell crank 152, which bell crank 152 is fulcrumed onthe frame piece 149 and has its other end articulated with a horizontallink 153 that is eccentrically connected by a crank pin 154 with a disk155 that is pro vided on a shaft 156 which extends through the frame 21and is provided on its outer end with a pinion 157 that is adapted tomesh with the gearwheel 96 whereby a vertical reciprocating motion maybe imparted to the bar 146.

The driven sprocket wheel 142 are secured to a shaft 158 which isprovided with a ratchet wheel 159 that is adapted to be engaged andmoved by a pawl 160- to move successive cross bars 140 underneath thepunching members 145 to permit such punching members in their downwardmovement to punch out the cones 144 that may be suspended within theholes 139 provided in the bars 140, dowel pins 161, that are pro videdon each end of the bars 140 being adapted to project within holes 162,provided in each of such bars 140 to insure that the punching members145 may always be accurately centered as they move downwardly throughthe holes 139.

The pawl 160 is secured to a swinging bar 1 163 which may be articulatedwith the frame 21, such bar 163 being eccentrically connected by a link164 with a crank disk 165 that is provided on the shaft 95 whereby itmay be moved backwardly and forwardly to impart a succession of forwardmovements to the endless cone conveyer such conveyer being at rest for asufficient length of time between successive movements to permit thepunching members 145 to be moved downwardly to punch out the cones 144from one of the bars 140 and then to be withdrawn and such conveyer thenbeing moved forward suliiciently to bringthe next successive bar 140underneath the punching members 145 while such members are raised.

In order that the cones 144 may be cared for when they are punched outof the holes 139 ,1in the conveyer bars 140 I have provided an endlessbelt composed of a pl; rality of vertically disposed flat plates 166that are secured at their top and bottom ends to endless sprocket chain167 and 168, respectively, and are adapted to pass around sprocketwheels 169 each of said plates having slidably associated therewith atube carrying member 170 that is provided at its bottom with anoutwardly projecting plate 171 upon which a tube 172, more clearly shownin Fig. 7, may rest and being further provided at intervals throughoutits length with pairs of grasping arms 173 that are adapted to grasp thetube 172 to hold such tube in an upright position such mem- Wardly toreceive the cones that are punched out of the holes 139 in the bars 140,the tube carrying members 170 being again lowered as the punchingmembers 145 are raised to permit the next cone conveyer bar 140 to bemoved to its position below the punching member.

The lower sprocket chain 168 is adapted to move in a lower guideway 178and each of the links of the upper sprocketchain 167 is rovided with anupwardly projecting guide piece 179 that is adapted to move in an upperguideway 180, more securely to hold the tubes 174 in their properposition.

The sprocket wheels 169 around which the tube carrying belt is adaptedto pass are spaced apart by a sleeve 181 to which they are secured, suchsleeve 181 being rotatably mounted on a vertical shaft 182 and a ratchetwheel 183 is secured to the lowermost side of the lower sprocket wheel169, such ratchet wheel 183 being spaced sufficiently above anothersimilar ratchet wheel 184 by means of a collar 185 to permit a pawl arm186 that is pivoted on the shaft 182 freely to move therebetween suchpawl arm 186 carrying a spring pressed pawl 187 that is adapted at alltimes to engage with the ratchet wheel 184 and a part of the time toengage with the ratchet wheel 183, secured thereto, and having its outerend connected by a link 188 with the swinging arm 165 whereby such pawlarm may be made to oscillate about the shaft 182 to move the pawl 187back and forth over the periphery of the ratchet wheel 184 to cause saidpawl to engage with the teeth of said ments to such wheel whichmovements occur concurrently with the movements of the cone carryingbelt which is moved by the .action of the pawl 160, the sprocket wheels169 and tube carrying "belt that is adapted to move on such wheels beingat rest when the ratchet wheel 184 only is engaged by the pawl 187 andsuch ratchet wheel 184 being provided at equidistant points on its topsurface with four lifting cams 189 that are,

each adapted to engage with and raise the pawl arm 186 as such pawl arm186 passes thereover to cause the pawl 187 to engage moved the ratchetwheel 184-sutficiently to cause another of the lifting cams 189 toengage with and lift the pawl arm 186. v The tube carrying belt in thedevice illustrated is adapted to move one space inunison with everyfourth movement of the cone carrying. belt whereby four cones may bedelivered into such tube each time such tube is stopped during itspassage under the bars 140 of the tube carrying belt such bars 140 eachbeing provided with six cone carrying apertures whereby a tube 174willhave stopped six times during its passage under the cone carrying beltand will have: received' four cones at each stop thus causing 24 conesto be placed in 'each tube although obviously the arrangement of theratchet wheel 184 may be such that any other desired number of conesmaybe placed in each a tube.

The mold carrying wheel moves constantly while the machine is inoperation and after the batter has been deposited in the cone shapedrecesses 40 of the molds 36 and the cores 42 have been thrust therein toform the cone then such cone is baked as the wheel revolves until thecam roller 72 on the lever arm ,71 approaches a position, as illustratedin Fig. 4, where it is engaged by the cam 73 to lift the cores 42slightly, which cores are again lowered immediately by the action of thecam 74 on the same cam roller 72, such raising and lowering of the cores42 serving to loosen them from the baked cones.

'As soon as the cores 42" have been loosened from the cones the camroller 86 on the lever arm 85 is engaged by the cam 88 and moved to sread the molds 36 apart, the cores 42 whloh have been loosened from thecone but still project therein holding such cone in a central positionand insuring that such cone. willbe loosened from such molds, 36 atytheproper instant of time to drop on;

into the 'conically shaped openings 40 of Y the molds by the cam 75 assoon asthey have passed over the depositing device, such cores 42 whenlowered being adapted to be'sufliclently'spaced from the walls of themolds to form a cone of the batter that has been deposited in suchmolds. I

During a period of operation of my machine the flame that is fed by gasfrom the pipes 54 and heatsthe cores is permitted to urn'continuouslybut the flame at the sides of the molds 36 that is fed by gas from thepipes 61' is adapted to be extiiiguished by the closing of the valve 63just before the baked cones are released and'is adaptedto be relightedby the flame Within the cores 42 when the'valve 63 is opened after themolds havebeen refilled the flame'at the sides of themolds thus beingextinguished during thetime that such molds are beingemptied andrefilled.
